Sincetheinstallationmethodaffectsthe service life,easeofmaintenance,frequencyofcheckandreapir,andoperating costs of engine, the following contents should be carefully examined before installing your engine.

For details, referto the separate “SALES MANUAL”-Engineering Information-.

5-1 MOUNTING

When installing the engine, its mounting position, coupling conditions with operating machines, and anchoringor supporting methodsmustbecarefullyexamined.Particularlywhendeterminingitsmountingposition,duecareshouldbetakento

assure the convenience of such routines as replenishment and checking of fuel and oil, checking of spark plug and breaker points, maintenance of air cleaner, and oil drainage.

5-2VENTILATION

The engine must be supplied with .fresh air for cooling and fuel combustion. If engine is operated with a cover or in a small

room,theengineroom is heated, causingvaporlock,deteriorationofoil,increaseof oil consumption,powerreduction, seizure, loss of engine life, and thus proper engine operation can be expectedno longer.

It is therefore necessary to provied a cooling air duct and a baffle plate for the purpose of preventing insufficient circulation of heated air after cooling engine and or temperature-rise of operating machines.

The temperature of engine compartment should be kept below 4OoC even in mid-summer.

5 3 EXHAUST GAS EVACUATION

Since the exhaust gas from engineis toxic, it must be exhausted outside if engine is operated indoors.

As the output power of an engine is considerably influenced by the length of exhaust duct, its diameter must be increased in proportion to its length.

5-4FUELSYSTEM

When fuel tank is separated from engine, it must be located so that its bottom surface lies within 5-50cm (2”-20”)above the fuel joint of carburetor. If the fuel tank is installed too low, fuel is not fed properly, and if it is too high, the carburetor may overflow.

For fuel piping, carefully examineit for heat conductivity, diameter, bending, andleakage through fittings so as to eliminate air lock and vapor lock.

It is recommended to minimize piping length. The standard ID of fuel pipe is 4-5mm (5,2”-13/64“).

Be carefulwiththefollowing items.

*Ilse a V-belt rather than a flat belt.

*Set the driving shaft of engine and the driven shaftof driven machine in paralled with each other. *Align the driving pulley of engine and the driven pulley of driven machine correctly with each other. *Mount the driving pulley as nearer to the engine as possible.
